Description

Technical Field

[0002] High-power wirewound resistors are made of nickel-chromium wire and constantan wire wound on porcelain tubes, and are divided into fixed and adjustable types. The characteristics of wirewound resistors are extremely high resistance accuracy, low noise during operation, stable and reliable, able to withstand high temperatures, and can still work normally at an ambient temperature of 170°C. However, they are large in size and have low resistance values, mostly below 100KΩ. In addition, due to structural reasons, their distributed capacitance and inductance are relatively large, and they cannot be used in high-frequency circuits. This type of resistor is usually used for voltage reduction or load in high-power circuits.

[0003] When processing wound resistors, constantan wire or nickel-chromium wire needs to be wound on an insulating frame. The common winding method is generally to manually clamp the insulating frame and then wind the constantan wire on the insulating frame. However, this method will have problems of uneven winding and low efficiency. Therefore, the utility model proposes a resistor winding machine for electronic components, which adopts a constantan wire pay-off machine and a winding robot arm. The constantan wire pay-off machine pays off the constantan wire, and the paid-off constantan wire is wound on the insulating frame, and the constantan wire is wound on it as the winding robot arm is driven, thereby realizing automatic winding of the constantan wire, and the winding is uniform and the winding efficiency is higher.
